The next day after this was so foggy that school was cancelled giving Izuku time to be Moon Rabbit, the first thing he did was to dispel the fog using flight's form to do it only to reveal a mysterious kid who created more. He asked Kero (who was with him) if it was the work of a card. And Kero said "Yes, cloud to be specific." Moon Rabbit then used fly's form to dispel the clouds again with this time, he sped forward with wood. The trick worked as he got to the person before it could dispel any more clouds and said "Return to the form that you were meant to be in! SAKURA CARD!" He then got a notification that school was back on and he noticed the cops were following him, so he said "Creation of Clow, lend your power to my key, Bestow the magic of the card unto my key! Cloud, Fog Up My Escape!" He then flew away now under the trail of a fog, not one that would last all day. So, school wasn't cancelled again. He then got off his costume at home and went to school in his usual get up. He later used cloud to escape his bullies undetected.
As soon as he was far away enough, he immediately became Moon Rabbit again. Went into town to help out via helping a lost kid get back to his mother, fixing a streetlight, help a family find their lost pet and stopping robberies. With one robbery stopping not going how he intended "Is this a film or a crime." Moon Rabbit said as he saw a (what he thought was a little girl) filming "Oh, there's a crime happening here. This company here is being run by rapist who use their power to rape their employes." Said the villain in question who was named Gentle Criminal, who threw out several elastic barriers. One he used to jump over Moon Rabbit, only for Moon Rabbit to say "Creation of Clow, lend your power to my key, Bestow the magic of the card unto my key! Wood, Trap Him. Then why haven't you called the police?" This produced a large cage made out of wood that formed around Gentle Criminal who simply made it elastic enough for him to escape, only for Gentle Criminal to then say "Did you try to call the police for the crimes you've stopped?" Gentle Criminal said and he and his partner La Brava tried to bounce away again, only for Moon Rabbit to say "Creation of Clow, lend your power to my key, Bestow the magic of the card unto my key! Cloud, Blind Him. At least I don't rob stores, robing employers from their paychecks." This ended up blinding Gentle Criminal who stopped despite getting directions for where to go from La Brava and he said "(chuckles) Good point, Moon Rabbit. Maybe this wasn't well thought out. La Brava stop the filming." "Maybe instead of a criminal, you can be a hero." Moon Rabbit said, only for Gentle Criminal to say "I can't, even ignoring the fact I committed crimes. I couldn't get high enough grades to make it into any hero school." He said sadly, only for Moon Rabbit to say "Then why don't you become a vigilancy, like me." "Hmm, became a hero just like I always wanted and it'll get me more remembered. I'm in, what do you say La Brava" Gentle Criminal said, only for La Brava to say "As long as I'm with you then I'm happy." They (after Moon Rabbit undid the cloud spell) then handed off the store manager and evidence of what he did to the police who arrested him and let off Gentle Criminal (who was now Gentle Hero who undergone a good costume switch by adding a cape that was white, that was all that changed) and La Brava (who also added a white cape but with pink highlights) because they returned the money.
